^^^^ you need to ground your Pbrake wire (the green one) and then you shouldnt get this message
I got it working, with 1 catch, i think that number (128, 16 ect.) is how many Km/hr, which makes sense because 16km/hr is rite around 10mph
i only realized this because i inadvertantly hit a little over 80 today and it gave me a warning and limited my options (128km/hr = roughly 80mph)
i am going to leave it at 128 though because if i am travelling over 80 i really dont think i need to be messing with my navi....just thought you guys would like to know that!
